Based on the micro-removal mechanism of the ultrasonic vibration-assisted grinding (UVAG), a new prediction model of alloy structural steel is proposed in this paper. In the grinding process, the abrasive grains mainly go through two stages: plowing stage and chip forming stage. Then, grinding force model of single grain under different material removal modes is established. The thickness of the abrasive grain, the number of grains involved in grinding, and the interference between the abrasive grains are essential factors that affect the grinding force. Considering the influence of ultrasonic vibration on these factors, the grinding force model of the grinding wheel is developed. The ultrasonic grinding experiments are conducted to validate this model. Findings show that the theoretically predicted results are consistent with the experimental results.
